An organic liquid flows at 25 cm/s through a heated tube 1.5 cm in diameter and 15
Question:
An organic liquid flows at 25 cm/s through a heated tube 1.5 cm in diameter and 15 cm long. The liquid properties are: ρ 900 kg/m3, μ = 1.7 cP, k = 0.135 W/m·°C, and = Cp 2.0 J/g · °C.
(a) Calculate jH using the equation for laminar flow and compare with the value obtained assuming turbulent flow at the same Reynolds number.
(b) If the calculated coefficient for laminar flow is greater than that for turbulent flow, what might be the reason for the difference? Is there an error in applying either the laminar flow equation or the turbulent flow equation to these conditions?
